Extreme Scientist Jamie Pafford demonstrates how to make fluorescent slime using household supplies.

A diluted mixture of school glue and water is mixed with a saturated solution of borax.

The glue is a polymer containing polyvinyl alcohol. These long chain polymer molecules become cross-linked together by the borax. Once cross-linked the polymer mixture becomes very sticky, or slime like.

The slime glows under ultraviolet light because of the fluorescent dye present in the highlighter. This slime does NOT glow in dark, it needs the energy of the UV light to excite the dye which then emits the brilliant green glow. Take away the UV light and the green glow disappears immediately.
